Turkey’s Syria operation cannot be limited to Afrin

Mevlut Cavusoglu spoke to reporters after meeting with his U.S. counterpart Rex Tillerson in Vancouver, Canada, where he was attending the Vancouver Foreign Ministers' Meeting on Security and Stability on the Korean Peninsula.

“Turkey’s precautions against YPG/PKK cannot be limited to only Afrin. There is also Manbij and east of the Euphrates River,” Cavusoglu said, adding the U.S. plan to establish a border guard in northwest Syria “irreversibly harms U.S.-Turkey ties”.

On Sunday, Ryan Dillon, spokesperson for the U.S.-led coalition against Daesh, announced plans to establish a 30,000-strong border security force in Syria with the SDF -- a U.S.-backed group drawn up largely of PYD/PKK terrorist elements.

The PYD/PKK is the Syrian offshoot of the PKK, which has been designated a terrorist organization by Turkey, the U.S. and the EU.

Since the mid-1980s, the PKK has waged a wide-ranging terror campaign against the Turkish state in which an estimated 40,000 people have been killed.

Cavusoglu said different opinions among the Pentagon and Centcom as well as different institutions and ministries in the U.S. regarding support for the SDF and the PYD/PKK have been causing the problem.

Noting past U.S. behavior regarding Manbij and Raqqah and its support to the PYD/PKK, Cavusoglu urged the U.S. to fulfill its promises.

"The promises made on Manbij and Raqqah have not been kept,” Cavusoglu said, referring to a promise by the U.S. that local councils would run the cities after they were liberated, but the PYD/PKK took control.

“In the same way, the promises about the steps that need to be taken after [the liberation of] Raqqah have also not been kept," he said.

"The U.S. has previously stated that the PYD/PKK was not their strategic partner, [that] in fact, they were only working together to defeat Daesh," he noted, urging the U.S. to stop supporting the group and to retrieve its weapons as Washington promised.

"As we can see, we have so many reasons to be skeptical, and we have enough reasons to take our own precautions," he added.

Earlier in the day, the Pentagon said the U.S. acknowledges Turkey's concern over its plans for a border security force in Syria and "close communications" with Turkey will continue.
